the rigor of GiveWell analysis versus your EV calcs is very different

Sort of a side question, but could you say what sort of thing you had in mind? i.e. the particular sense in which GW's calc are rigorous. I ask because I find their assumptions odd/pretty disatisfying and think they leave out loads of stuff. I mean to write about when I find time.

This isn't to say my calculations are more rigorous than theirs. GW have loads more detail.

I think I'd broadly model rigor on a framework like this as the standard deviation of the estimate of cost-effectiveness when using a X% credibility interval (where X% is consistent across all compared intervals). Models with lower standard deviations can be said to be more rigorous as there are less (known) sources of uncertainty.
